【Abstract】 In the field of temperature measurement precise measurement of low and super low temperature is always a very important subject This paper introduced several new types of cryogenic temperature sensors Some new types of sensors have been developed and tested The experimental results show that these types of sensors can substitute for thermistors and thermocouples in the field of the test of rocket engines and they behave better than thermistors and thermocouples in the characteristics such as precision,stability,interchangeability,self heating,and etc更多还原
